This mushroom-shaped treehouse just won Shed of the Year 2017

Mushroom House has won the coveted Cuprinol Shed of the Year competition 2017.

Millions of Brits across the nation tuned in to watch George Clarke announce the winner during the final episode of Channel 4's Amazing Spaces Shed of the Year – and it was Ben Swanborough's hand-built treehouse that took the final prize.

The Mushroom House, which is the 10th anniversary winner of the annual shed event, beat stiff competition following a record-breaking 2,963 entries and 26,571 public votes.

Following a tense and lengthy deliberation between the show's judges – competition founder, Uncle Wilco (Andrew Wilcox), George Clarke, and the Amazing Spaces team William Hardie, Laura Clark and Max McMurdo – a distinct favourite emerged.

Ben built Mushroom House after his 12-year-old daughter handed him £500 of her own money to create a magical hang-out space in the shape of a mushroom.

Perfect for a treetop sleepover or afternoon tea party, Mushroom House is full of quirky touches, including its own trap door, a hidden treat shelf and glass floor overlooking a stream at the bottom of the garden.

'Your garden really can become a 5th room for all the family to enjoy.'

Marianne Shillingford, creative director at Cuprinol, said: 'Ben has proved that you just need a little motivation and vision to create a truly stunning space at the bottom of your garden. His shed was definitely a worthy winner for the competition's landmark year.'

As well as winning the coveted title, Ben won £1,000 courtesy of sponsors Cuprinol, £100 of Cuprinol products, a winner's plaque and a giant crown for his shed.

Having also won the Cabin and Summerhouse Category in episode one, winner Ben said: 'When we started the project we never could have dreamed we'd be here now. We've already made so many lovely memories in our shed, and now have so many more from the competition! There were so many innovative and amazing sheds in the running, and we're absolutely thrilled to have been crowned Shed of the Year 2017!'

Marianne added: 'This year's entries have really stood out from the crowd and show that your garden really can become a 5th room for all the family to enjoy. There are some really simple ways to recreate these looks in your own garden and we hope the competition will inspire the nation to make the most of their outdoor space.'

Pricklebums is an old garden summerhouse that was renovated and converted into a hedgehog hospital, for housing sick, injured or orphaned hedgehogs. This little shed sanctuary is extremely small (roughly 2m square), but can house up to 22 sick hedgehogs.

Built with only sustainable materials, this off-grid wee tower is hidden in the woodland by the owner's cottage. Based in the Ardgour, which is known for its abundance of local wildlife and incredible dark skies, this shed is the perfect escape from the modern world.

After being born with one hand himself, Stephen noticed the huge number of children that had no access, poor choice, or that were unable to afford an artificial arm, so at Team Unlimbited, Stephen designs, prints, builds and delivers 3D printed hands and arms to children completely free, all in his spare time.

Designed as an old-fashioned style fire station, The Engine House, is full of fire service memorabilia. Features include a muster bay for firefighting uniforms, watch room, two workshops, fireman's pole, seating bay and mess room.

Built entirely from discarded material around the family's farmyard, this studded wooden structure is used by David and his son to manufacture wooden items from trees cut down in their tree surgery and forestry business.

Built onto a trailer, Letsby Avenue is a 1940s Civilian Police Station Living History display which tours around the UK to 1940s events and Police open days. The public can come inside to learn all about policing during World War Two and to see the equipment, posters and paperwork relevant to policing during that period.

At ground level this is a very practical shed storing garden tools and family bikes. But under some rugs is a secret entrance to an underground bunker, also known as a man cave. The hideaway has pretty much everything including a Sky TV, PlayStation, drum kit and band practice area.
